Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528340, here are decompositions:

3 + 33528337 = 33528340
71 + 33528269 = 33528340
173 + 33528167 = 33528340
191 + 33528149 = 33528340
317 + 33528023 = 33528340
347 + 33527993 = 33528340
359 + 33527981 = 33528340
431 + 33527909 = 33528340

Showing the first eight; more decompositions exist.
